503-505 S Main Street
W Commercial is pleased to present 503 & 505 South Main Street for sale at $550,000 — a two-unit mixed-use property on a prominent corner at the southern gateway to downtown Sebastopol, with glass storefront frontage onto Highway 116. The ground level (503) is a storefront commercial suite of approximately 900 SF with corner glass and street-level signage identity; the second level (505) is a self-contained one-bedroom, one-bath residence of approximately 960 SF with bay-window corner exposure.
The property is a natural fit for an owner-user: anchor the street-level commercial suite with your own business and let the residence above help offset the cost of ownership. Built in 2006 with wiring and plumbing updated in 2024, it forms part of the 501 South Main Street Subdivision, with three reserved spaces in a private lot off Walker Avenue. This offering is the 503/505 unit only.
